Don't confuse a belligerent and aggressive attitude with the strength, training, and conditioning needed to prevail in a fight. How do you know you have the Will To Win, if you don't even have the will to train?

Eventually, with the right tactics...I mean scavenging from the fallen of course.The idea being that I would have something to shoot almost any ammo I can find. And if I find ammo I don't have a gun for, it is probably close by.

Yup. .22 and 20ga for hunting, the AK can take anything really large, and the AK and AR can both serve as defensive carbines. I've been setting aside x% of my pay, which gets divvied into "firearms building" "ammo" and "other preps."
